Command prompt utility to copy files for specified time range

 I’ve tried to find an utility that will allow to copy files from big folder for specified time range.
 The  discussion in experts-exchange suggested to use RoboCopy
Robocopy FolderFrom FolderTo /MINAGE:20091125 /MAXAGE:20091124
Note that for 1 day selection  MINAGE should be one day BIGGER than required date.
I still wish to find utility that will allow to specify time, rather than full date.
The same discussion has batch file example, that possibly can be used to filter time as well.
